Description

Technical Field

[0001] This utility model relates to the field of catering equipment technology, and more specifically, it relates to a slag removal gas washing machine. Background Technology

[0002] In the tableware washing industry, the residue removal device is a key piece of equipment in the tableware washing line, and its residue removal effect directly affects the overall quality and efficiency of tableware washing. Currently, most common residue removal devices on the market, such as rotary filter type and high-pressure water flushing type, rely solely on water flow for residue removal. They use a high-pressure water pump to pressurize water, which is then sprayed onto the surface of the tableware through nozzles, using the impact force of the water flow to wash away residue, or using water flow to assist the filter screen in separating residue.

[0003] However, this single water rinsing method has a significant efficiency bottleneck when dealing with sticky residues or residues that are tightly bound to the surface of tableware. For example, when dealing with starchy food residues such as rice and noodles, these residues easily form a sticky paste upon contact with water, adhering tightly to the surface of the tableware, and water rinsing alone is insufficient to quickly remove them. Similarly, when there are sticky food residues such as melted cheese or syrup on the tableware, these substances adhere to the surface like glue, and the impact of the water flow is insufficient to break down their adhesion, resulting in poor rinsing. Furthermore, for meat residues containing oil, the grease forms an oil film on the surface of the tableware, making the residue even more tightly bound to the tableware, and water flow is unlikely to completely separate it.

[0004] With the development of the catering industry, the demand for tableware cleaning is increasing, and the requirements for cleaning efficiency and quality are constantly improving. The existing single water flow slag removal method can no longer meet the industry's needs, and there is an urgent need for a slag removal device that can more efficiently handle various stubborn residues. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a slag removal air washing machine to solve the technical problem that existing slag removal devices cannot efficiently remove residues that are highly viscous or tightly bonded to the surface of tableware by relying solely on water flow.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A slag removal air scrubbing machine includes a frame, a cleaning tank for holding tableware to be cleaned and cleaning liquid on the frame, and a filter tank for receiving the mixture of residue and cleaning liquid overflowing from the cleaning tank on the frame. Several water nozzles and several air nozzles are provided at the bottom of the cleaning tank. A booster pump and a blower are provided on the frame. The inlet of the booster pump is connected to the filter tank, the outlet of the booster pump is connected to the several water nozzles, and the outlet of the blower is connected to the several air nozzles.

[0008] Optionally, the water nozzle is a long, narrow tube with several water outlet holes on both sides.

[0009] Optionally, the air nozzle is a long tube with several air outlet holes on both sides.

[0010] Optionally, both the water nozzle and the air nozzle can be long, rectangular tubes.

[0011] Optionally, several water nozzles and several air nozzles can be arranged alternately.

[0012] Optionally, both ends of the water nozzle and the air nozzle are provided with angled openings.

[0013] Optionally, a heating element is installed at the bottom of the washing tank.

[0014] Optionally, the bottom of the cleaning tank is recessed to form a heating groove for housing the heating rod and preventing it from burning dry.

[0015] Optionally, a first filter screen is provided at the top of the heating tank to prevent residue from entering the interior of the heating tank.

[0016] This invention has the following beneficial effects: During operation, the booster pump pressurizes the pre-filtered cleaning liquid in the filter tank, forming a high-pressure water flow through the water nozzles at the bottom of the cleaning tank. Simultaneously, the blower sprays compressed gas at high speed through the air nozzles, creating a powerful air-water mixing flushing system at the bottom of the cleaning tank. For sticky substances such as rice, cheese, and syrup, as well as meat residue with attached grease, the high-frequency air waves generated by the compressed gas can precisely impact the adhesion interface between the residue and the tableware surface, breaking the intermolecular forces and loosening the originally tightly bound residue. At the same time, the high-pressure water flow uses its strong kinetic energy to perform a secondary flushing of the residue, completely washing the loosened residue away from the tableware surface. The two work together to form a residue removal capacity far stronger than that of a single water flow. In addition, the water and air nozzles centrally arranged at the bottom of the cleaning tank allow the air-water mixture to act directly on the residue with the shortest path and the greatest impact force, preventing the residue from settling and clogging the nozzles. The circulation system between the filter tank and the cleaning tank allows the cleaning liquid to be reused after preliminary filtration, ensuring a continuous and stable air-water mixing rinsing effect, reducing water waste, and lowering the pressure on sewage discharge and treatment. This achieves efficient removal of stubborn sticky residue and optimizes and upgrades the cleaning system. Attached Figure Description

The accompanying drawings show embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] This utility model provides a slag removal gas scrubbing machine, such as Figure 1-5 As shown, the system includes a frame 1, a washing tank 2 for holding tableware to be washed and washing liquid, and a filter tank 3 for receiving the mixture of residue and washing liquid overflowing from the washing tank 2. Several water nozzles 4 and several air nozzles 5 are provided at the bottom of the washing tank 2. A booster pump 6 and a blower 7 are provided on the frame 1. The inlet of the booster pump 6 is connected to the filter tank 3, the outlet of the booster pump 6 is connected to several water nozzles 4, and the outlet of the blower 7 is connected to several air nozzles 5.

[0026] Specifically, the frame 1, cleaning tank 2, and filter cake tank 3 are all made of stainless steel and are fixed together by welding. The top of the cleaning tank 2 is bent to form an overflow plate 25, which prevents the backflow of residue and ensures the cleaning effect. Two water nozzles 4 and three air nozzles 5 are directly or indirectly fixed at the bottom of the cleaning tank 2. The booster pump 6 and the blower 7 are conventionally installed on the frame 1 and located below it. The outlet of the booster pump 6 is connected to the two water nozzles 4 through a connecting pipe, and the inlet of the booster pump 6 is connected to the bottom of the filter cake tank 3 through a connecting pipe. The outlet of the blower 7 is also connected to the air nozzles 5 through a connecting pipe, and a gas-liquid check valve (not shown in the attached diagram) is installed on the connecting pipe to prevent the cleaning fluid from flowing back into the blower 7 when the machine is stopped, which would affect the next use of the equipment. A water inlet pipe (not shown in the attached diagram) for introducing cleaning fluid (such as tap water) is installed at the top of the cleaning tank 2. After the residue and cleaning fluid are mixed, a residue-cleaning fluid mixture is formed. The less dense residue floats at the top of the cleaning tank 2, and the more dense residue settles at the bottom of the cleaning tank 2. The top of the filter tank 3 is detachably snapped with a second filter screen 31. The residue-cleaning fluid mixture overflows from the top of the cleaning tank 2 through the overflow plate 25 onto the second filter screen 31. At this time, the larger residue in the residue-cleaning fluid mixture is filtered out by the second filter screen 31, and the smaller residue enters the interior of the filter tank 3 with the cleaning fluid. A third filter screen 33 is further installed at the bottom of the filter tank 3 to filter out the aforementioned smaller residue. The residue-cleaning fluid mixture filtered by the third filter screen 33 is transported to the cleaning tank 2 by the booster pump 6.

[0027] During operation, the booster pump 6 pressurizes the pre-filtered cleaning liquid in the filter tank 3, creating a high-pressure water flow through the water nozzle 4 at the bottom of the cleaning tank 2. Simultaneously, the blower 7 sprays compressed gas at high speed through the air nozzle 5, constructing a powerful air-water mixing flushing system at the bottom of the cleaning tank 2 to wash away food residues attached to the surface of the tableware. For sticky substances such as rice, cheese, and syrup, as well as meat residues with attached grease, the high-frequency air waves generated by the compressed gas can precisely impact the adhesion interface between the residue and the tableware surface, breaking down the intermolecular forces and loosening the originally tightly bound residues. At the same time, the high-pressure water flow uses its strong kinetic energy to perform a secondary flushing of the residues, completely washing the loosened residues away from the tableware surface. The two work together to form a residue removal capacity far stronger than that of a single water flow. In addition, the water nozzles 4 and air nozzles 5, which are centrally arranged at the bottom of the cleaning tank 2, allow the air-water mixture to act directly on the residue with the shortest path and the greatest impact force, preventing the problem of residue settling and accumulating at the bottom and causing nozzle blockage. The circulation system of the filter tank 3 and the cleaning tank 2 allows the cleaning liquid to be reused after preliminary filtration, which not only ensures a continuous and stable air-water mixing flushing effect, but also reduces water waste and reduces the pressure on sewage discharge and treatment, achieving efficient removal of stubborn sticky residue and optimization and upgrading of the cleaning system.

[0028] Furthermore, the water nozzle 4 is a long tube with several water outlet holes 41 on both sides of the tube.

[0029] Furthermore, the air nozzle 5 is a long tube, and several air outlet holes 51 are provided on both sides of the tube.

[0030] Furthermore, both the water nozzle 4 and the air nozzle 5 are long, rectangular tubes.

[0031] Furthermore, several water nozzles 4 and several air nozzles 5 are arranged alternately.

[0032] Furthermore, both ends of the water nozzle 4 and the air nozzle 5 are provided with oblique openings.

[0033] like Figure 5 As shown, both the water nozzle 4 and the air nozzle 5 are made of stainless steel and are long, narrow tubes, which can be cylindrical or square. The water nozzle 4 has four water outlets 41 on both sides of its tube; the air nozzle 5 has three air outlets 51 on both sides of its tube. The tubes of the water nozzle 4 and the air nozzle 5 are arranged alternately, with adjacent water outlets 41 and air outlets 51 staggered to combine water and air flow and generate high-frequency air waves to flush away residue. Both ends of the water nozzle 4 and the air nozzle 5 have angled openings (shown in the attached diagram), with the openings facing upwards to facilitate the flushing of residue and prevent denser residue from settling at the bottom of the cleaning tank 2 and clogging the water outlets 41 and air outlets 51.

[0034] Furthermore, an electric heating rod 21 is installed at the bottom of the cleaning tank 2.

[0035] Furthermore, the bottom of the cleaning tank 2 is recessed downward to form a heating groove 22 for accommodating the heating rod 21 and preventing the heating rod 21 from burning dry.

[0036] Furthermore, a first filter screen 23 is provided on the top of the heating tank 22 to prevent residue from entering the interior of the heating tank 22.

[0037] like Figure 2-3As shown, the heating rod 21 heats the cleaning fluid, enhancing its cleaning power. The heating tank 22 is located below the water nozzle 4 and the air nozzle 5, ensuring that the cleaning fluid in the cleaning tank 2 preferentially enters the heating tank 22 to submerge the heating rod 21, preventing it from burning dry due to insufficient cleaning fluid and thus ensuring equipment safety. The first filter screen 23 prevents residue from entering the heating tank 22, preventing residue from adhering to the surface of the heating rod 21 due to high-temperature sintering. This ensures that the thermal resistance between the heating rod 21 and the cleaning fluid does not increase significantly with prolonged use, and also facilitates cleaning of the heating tank 22. Furthermore, a float switch (not shown in the attached diagram) is installed in the cleaning tank 2, located above the heating rod 21. When the water level in the cleaning tank 2 is lower than the float switch, the water supply pipe automatically replenishes tap water into the cleaning tank 2, i.e., the water supply pipe on which the float switch is installed.

[0038] To prevent the water level in the filter cake tank 3 from overflowing onto the ground due to excessively high water levels, a second extension pipe 32 is installed inside the filter cake tank 3 to adjust the water level. The second extension pipe 32 is a telescopic pipe that can be stretched to a length and compressed to a short length. The top end of the second extension pipe 32 is an inlet, and the bottom end is an outlet connected to an external drainage pipe. Typically, the top end of the second extension pipe 32 is located below the second filter screen 31. Similarly, to adjust the water level in the cleaning tank 2, a first extension pipe 24 is installed inside the cleaning tank 2. The upper end of the first extension pipe 24 penetrates the first filter screen 23. When the inlet at the top of the first extension pipe 24 is lower than the overflow plate 25, the cleaning liquid cannot overflow from the cleaning tank 2 to the filter cake tank 3; when the inlet at the top of the first extension pipe 24 is higher than the overflow plate 25, the cleaning liquid can overflow from the cleaning tank 2 to the filter cake tank 3. After working for a period of time, a large amount of residue (i.e., suspended matter) with a density similar to that of the cleaning liquid will be suspended in the middle of the cleaning tank 2. Compressing the length of the first pull tube 24 will discharge this part of the residue into the external drain pipe, thereby improving the cleaning cleanliness.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
